I remember this sickening story. These two young sisters in there 20's were best friends, Alice and Betty I'll call them for this story. Alice's father, a brother, was a widower, so Betty married Alice's father. Alice and Betty are best friends and all of the sudden she's marrying her father, but they remained friends though and even had babies around the same time !! This brother wasn't exactly the "handsomest brother on the planet", remember what Al Roker looked like before he lost all his weight, imagine that look on a fifty something body I imagine this old geezer is either dead now or in a nursing home. I don't even know if the marriage lasted because they relocated to another state in the 1990's.
So this pedo-brother must've been checking Betty for quite some time and just waited until he felt it was safe to make his move and when he did she fell head over heels for him. That's the sickest part about the whole thing to me.
